QR Redirector [qr-code] Shortcode

The QR-Redirector plugin shortcode ‘qr-code’ generates a QR code image. It does this by extracting the ‘id’ attribute from the shortcode and retrieving the QR image URL associated with that post ID. If no ‘id’ is specified, no output is displayed.

Shortcode: [qr-code]


Here is a list of all possible qr-code shortcode parameters and attributes:

  • id – Unique identifier for the specific QR code image

Examples and Usage

Basic example – Display a QR code by specifying the post ID

[qr-code id=2 /]

Advanced examples

Display multiple QR codes by specifying different post IDs. Remember, each QR code should be associated with a unique post ID.

[qr-code id=2 /]
[qr-code id=3 /]
[qr-code id=4 /]

Note: If no ID is specified or if the specified ID is not associated with any QR code, the shortcode will not display anything.

Also, ensure that the ‘qr_image_url’ custom field is set for the specified post ID, as this is where the shortcode retrieves the QR code image URL.

Remember to replace ‘2’, ‘3’, and ‘4’ with the actual post IDs that are associated with the QR codes you want to display.

PHP Function Code
